Abstract (en)
[origin: US4541238A] The process comprises the comparison of the flows of fuel and oxidizer measured at the outlet of the turbopumps with a set value corresponding to the optimum value of the mixture. The set value is periodically modified in dependence on the volumes of fuel and oxidizer remaining in the tanks. The control system for carrying out the process comprises a control valve controlled by an electronic device processing the measurements and disposed in a fuel or oxidizer supply pipe of a driving gas generator for the turbine of a turbopump or in the gas supply pipe of a turbopump, or disposed between the two pipes supplying the same fuel or oxidizer two driving gas generators, or between the gas outlets of the two turbines of the turbopumps.
